Abstract

A method for forming an applicator comprises steps of: creating a digital geometric representation of the structure, the target structure having a flatness ratio; forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface; and disposing an active agent upon the target structure contacting surface of the applicator.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A method for forming an applicator, the method comprising steps of:
 creating a digital geometric representation of a target structure, the target structure having a flatness ratio; 
 forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface; and 
 disposing an active agent upon the target structure contacting surface of the applicator; and 
 sizing the outer perimeter of the applicator to the target structure contacting surface. 
 
     
     
       2. The method according to  claim 1 , wherein the step of: forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface comprises: creating a physical representation of at least a portion of the target structure according to the digital geometric representation; forming the applicator using the physical representation of the target structure, the applicator having a target structure contacting surface. 
     
     
       3. The method according to  claim 2 , wherein the step of: creating a physical representation of at least a portion of the target structure according to the digital geometric representation, further comprises creating a set of physical representations corresponding to a set of portions of the digital geometric representation of the target structure. 
     
     
       4. The method according to  claim 2 , wherein the step of: creating a physical representation of at least a portion of the target structure according to the digital geometric representation, further comprises creating active agent deposition channels as part of the physical representation. 
     
     
       5. The method according to  claim 2 , wherein the step of forming the applicator comprises thermoforming at least a portion of the applicator using the physical representation of the target structure. 
     
     
       6. The method according to  claim 2 , wherein the step of: creating a physical representation of at least a portion of the target structure according to the digital geometric representation, further comprises creating a physical representations corresponding to an altered digital geometric representation of the target structure. 
     
     
       7. The method according to  claim 2 , wherein the step of: creating a physical representation of at least a portion of the target structure according to the digital geometric representation, further comprises creating a physical representation of at a portion of the target structure having a flatness ratio which is higher than the flatness ration of the target structure. 
     
     
       8. The method according to  claim 2 , further comprising the step of removing a portion of the formed applicator. 
     
     
       9. The method according to  claim 2  further comprising the step of creating a digital diagnostic scan of the target structure. 
     
     
       10. The method according to  claim 9 , further comprising the step of disposing the active agent upon the applicator according to the digital diagnostic scan. 
     
     
       11. The method according to  claim 1 , wherein the step of: forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface comprises: creating a physical representation of at least a portion of the negative of the target structure according to the digital geometric representation; the physical representation having a target structure contacting surface. 
     
     
       12. The method according to  claim 11 , wherein the step of: creating a physical representation of at least a portion of the negative of the target structure according to the digital geometric representation, further comprises creating a set of physical representations corresponding to a set of portions of the negative of the target structure according to the digital geometric representation. 
     
     
       13. The method according to  claim 11 , wherein the step of: creating a physical representation of at least a portion of the negative of the target structure according to the digital geometric representation, further comprises creating active agent deposition indicia as part of the physical representation. 
     
     
       14. The method according to  claim 11 , wherein the step of: creating a physical representation of at least a portion of the negative of the target structure according to the digital geometric representation, further comprises creating a physical representations corresponding to an altered digital geometric representation of the target structure. 
     
     
       15. The method according to  claim 11 , wherein the step of: creating a physical representation of at least a portion of the negative of the target structure according to the digital geometric representation, further comprises creating a physical representation of at a portion of the negative of the target structure having a flatness ratio which is higher than the flatness ratio of the target structure. 
     
     
       16. The method according to  claim 11 , further comprising the step of removing a portion of the created applicator. 
     
     
       17. The method according to  claim 11  further comprising the step of creating a digital diagnostic scan of the target structure. 
     
     
       18. The method according to  claim 17 , further comprising the step of disposing the active agent upon the applicator according to the digital diagnostic scan. 
     
     
       19. A method for forming an applicator, the method comprising steps of:
 creating a digital geometric representation of a target structure; 
 forming the applicator using the digital geometric representation of the target structure, the applicator having a target structure contacting surface; and 
 disposing an active agent upon the target structure contacting surface of the applicator; and 
 sizing the outer perimeter of the applicator to the target structure contacting surface.
